7 Claims.

This invention relates to improvements in ink fountain typing machines and particularly to improvements in mechanism for turning the ribbon spools of such machines, and it relates to improvements in the design of the ink reservoirs and inking mechanisms and also to improvements in the spools themselves of such typing machines.

. One of the principal objects of this invention is to provide mechanism and spools for ellieiently. inking and winding a typing machine ribbon approximately ninety yards in length in order that sharp, even, substantially uniform writing may be had during the entire life of the fabric of such extra long typing machine ribbon.

Another object is to move said ribbon from a vertical spool, stationed adjacent the key-board of the typing machine, through suitable guides and in contact with inking means to the vibrator and to the other spool, without at any time havconstruction that movement may be selectively transmitted to either spool, the shafting for transmittin rotary motion to the spools being so constructed and arranged that power may be transmitted to either spool with the same amount 1 of force when the keys of the machine are being used.

Other objects will appear hereinafter from the following description and claims.

In the accompanying drawings:

Tests made during the past eighteen months in various parts of the United States of the ink fountain typing machines of my United States Patent No. 2,158,944, show a great desire on the part of business men and stenographers for a machine utilizing a ribbon many times the length of the standard 12 yd. inked ribbon. Short ribbons are regarded as a nuisance. It is much more expensive to purchase seven ribbons each 12 yds. long, on seven spools and each spool wrapped in foil and each spool packed in a separate box than it is to purchase one ribbon eightyfour yards long, or thereabouts, wound on one spool and packed in one box. It is a well known fact that typists dislike to take oil an old, worn ribbon and replace it with a freshly inked ribbon. In most ofllces the new ribbons write much too heavyand smeary and after a very limited use, the appearance of the writing is entirely different and soon the ink supply is exhausted and the writing is dim. It is unreasonable for a ribbon to be used as an ink reservoir, to carry a large, reserve supply of ink. The writing should be very sharp and clean-cut and printlike in appearance at all times from the beginning of use of a new ribbon until the fabric itself is badly worn. The writing should stay substantially uniform in appearance. To secure improved wrlting results from a typing machine and to secure results which meet the great need and demand of the hundreds of thousands of rofessional typists and stenographers of this country alone, it has been necessary to provide a very long ribbon which may be extremely thin and tough and carrying just enough ink at the start for beautiful, easily legible, printllke impressions. By means of 'my improved inking mechanism and improved design of the ink reservoirs and of the spools themselves and the spool-driving means, it is now possible'to utilize a ribbon which may be as long as ninety yards. and, this ribbon moves back and forth past the typing position steadily and easily and no undue load is placed upon the carriage spring. "Hie fact is that by using the improved driving means for the spools and by placing the spools in the new position shown in Figs. 1 and 3, the typist does'not exert any more energy or force in operating the typing machine of my new construc- 1 or elite type machine.

tion than in operating the conventional typewriter of the usual type which employs usual spools lying in a horizontal position and winding only a 12 yd. ribbon. It is a well known fact that a late model typewriter of usual construction and design is usually demonstrated when equipped with a very lightly inked ribbon capable of writing but a short time. The late model typewriter will do very ugly writing if a heavily inked, conventional cotton ribbon is used in a pica type Even 'a very old model will do neat writing if equipped with a lightly inked silk ribbon. Not one typist in ten thousand gets to use a lightly inked silk ribbon even though my U. S. patent covering the silk ribbon expired many years ago. By reason of my present invention, the business man may now save considerable expense in connection with the oper tion of the typewriters of his ofiice since he may now purchase lightly inked silk ribbons of great length and utilize one such ribbon for at least three years, since ink willbe fed to the ribbon during operation of the typing machine by means of the improved inking mechanism and the ribbon will give just as neat and attractive looking impressions at the end of three years as when the fabric was new. If the typing machines used are of the type wherein there is no cutting blow against the ribbon fabric but simply a pressure, then the long ribbon hereinabove mentioned may be utilized for six or seven years. The present invention gives a vastly increased quantity of easily legible writing at greatly reduced expense to the business man and at great saving of the eye-sight of the reader. Sharp, clean-cut writing of rich color is much easier to read than heavy, ugly, smeary impressions from a new, too heavily inked ribbon. It is believed that the new, more efficient mechanism meet a demand now existing in all busy oifices for better writing results at lower cost. The professional typist now using the conventional typewriter equipped with a ribbon of conventional sort, is up against the same difiiculty she was forty or fifty years ago, viz.: The writing is too ,heavy at the start and its appearance is constantly changing. All this is amateurish. It is unscientific.

, It is common knowledge among professional stenographers that a typewriter ribbon usually writes differently near the ends than in the rest of the ribbon during the wear-down of said ribbon. By having the ribbon approximately seven times as long as the usual twelve yard ribbon, the typist seldom writes along the portions of the ribbon near the ends and, therefore, this defect is overcome; I

The present invention disclosesv a marked improvement over the mechanism of my United States Patent No. 2,158,944, since the position of the inking wheels has been changed and the said wheels place ink on the ribbon more efficiently near the ends of the path marked on the ribbon by-the type faces during use of the machine. In an ideal typing machine, the inking wheels would be located at the typing position, i. e. where the ribbon vibrator now is. By entirely doing away with the usual vertical shafts and the conventional typewriter spools at the upper ends of said shafts, and by removing the housing about said spools, it has been possible to place the ink reservoirs approximately where the spools usually are located and the inking wheels have been placed much nearer the typing position. I utilize two ink reservoirs and two inking mechanisms, all of which are located much closer to the ribbon vibrator or typing position. This is a big improvement overthe invention of said United States Patent 2,158,944 in many respects. In that invention the portion of the inked ribbon which extended from the vibrator l8 to the inking wheel 39 when thespool near said inking wheel 30 was empty, never received ink except from one of the inking wheels. The distance from vibrator l8 to inking wheel 30 of that invention is much greater than the distance from vibrator l8 to inking wheel of the present invention. Therefore the portion of the ribbon which only receives ink from one inking wheel is very much shorter in the, present invention. A careful study of this matter discloses that when ribbon spool I9 is empty and spool 20 is approximately full of ribbon, and when the ribbon begins to travel into spool 19, that portion of said ribbon which extends from the left inking wheel tothe vibrator and to the right inking wheel, will only receive ink from the left inking wheel. Therefore the closer the two inking wheels are to vibrator l8, the shorter will be that portion of the ribbon near the ends which receives ink from only one inking wheel. Another advantage of the present invention is that approximately 84 yds. to yds. of ribbon is utilized and the ribbon travel is slower than normal, so the typist will seldom reach the end portions of the ribbon anyhow. I In the construction shown in the various figures, a usual, conventional typing machine has been utilized. Much of the usual machine has been discarded and new, improved mechanism has been utilized in the space formerly occupied by the discarded parts. Y

In Fig. 1, l5 represents the frame of a typing machine having a platen l0, and I1 represents the writing ribbon which is guided into operative relation to the platen by means of vibrator iii, of usual construction. I9 and 20 represent the ribbon spools which lie in a vertical position and which are of new design. They are actuated by new means and the ribbon is fed from one spool to the other, back and forth in the machine. As shown in Fig. 1, the typing machine is provided with an ink reservoir 22 and an inking wheel 30 which occupy the space in the machine usually occupied by the ribbon spools and housing. Only one reservoirand only one inking wheel and inking mechanism may be used if preferred. The inking mechanisms may be secured to base plate 23 which is securely fastened to the frame of the typing machine with screws.

In the particular construction illustrated in Fig. 1, the writing ribbon I1 is guided in any suitable manner, for example, by means of slotted guides 25 and 26, each of which has a lower portion fastened, for example, by means of a nut, to plate 8.

Additional guides are shown in the form of Q rollers I25 which also act to keep tension on the ribbon when it is unwinding from a spool. The

ribbon is kept smooth and tight and flat so that it winds up under considerable tension and occu pies much less space in the spool and it does not become creased and wavy. The pigment ink may be applied to the ribbon by means of inking wheels 30 which are mounted upon shafts 35. The lower end portions of shafts 35 are journalled through-plate 8. Close to the base plate 8 each shaft 35 carries a gear 31.

The portion of the ribbon ll which is in contact with inking wheel 30 has such frictional engagement therewith that during movement of assays? each wheel 30 is formed so as to create a good.

frictional binding between the said ribbon and the inking wheels 30, as ink is placed on said ribbon. 4

A detailed description of the inking rollers. SI which extend through the housings 43 may be found on page 2 of my United States Patent No. 2,158,944, as well as a detailed statement of the mixing of the ink in reservoir by means of agitators ii, and the travel of said ink from said reservoir to the periphery of inking wheel 30. It

' passes through a screen or tape 3 5, if preferred,-

when it goes from the inking roller Si or this screen may be omitted entirely. A detailed description of said screen also appears in said patcut. The roller 53 may be made of metal. The space between the periphery .of roller 51 and housing 43 may be approximately .006 of an inch for writing that is sharp and clean-cut with pica or elite type for fine correspondence work, or the opening or space may be smaller for micro type work, or larger for bulletin type writing. It is only desirable to have the roller 5i rotate when ink is to be fed to the periphery of inking wheel 30 for transferto a face of writing ribbon I7. Therefore much of the time inking wheel 30 is moved out of contact with the ink by means of arm 5. Usually I feed ink to the ribbon as it passes from the typing position towards the winding spool. This allows the ink to have more time usually to be absorbed and to penetrate the ribbon fabric.

The ribbon spools I9 and 20 are of such size that they may accommodate a writing ribbon of thin silk approximately 84 yds. to 90 yds. long. These spools are rotatably mounted upon pins I18 projecting forwardly from the typewriter and ro-,- tatably held upon the pins or spindles by winged nuts II9. It will thus be seen that the spools are rotatably mounted in a vertical position close to the front of the typewriter, near the key-board, and each is located adjacent one side of the typewriter in spaced relation to each other transversely of the typewriter. Rotary motion may be selectively transmitted to the ribbon spools I9 and 20, and the improved mechanism for accomplishing this includcs a drive shaft I02, which is rotatably mounted at one side of the type;- writer, and at its rear end carries a small gear or pinion IOI, vmeshing with the gear or pinion formed by teeth extending about the drum I housing the usual carriage driving spring, by means of which movement is imparted to the carriage of the typing machine, The rear end portion of the drive shaft I02 is rotatably mounted through a bracket .I2I carried by the frame of the typewriter. The forward portion of the drive shaft is rotatably mounted through a bracket I23 carried by the cross-bar I22 of the typewriter fram which carries the spindles II8 upon which the ribbon spools I9 and 20 are mounted for reeling the ribbon. The worm I03,

carried by drive-shaft I02, and adjacent the front end thereof, meshes with a worm gear I00 carried by a rotatable shaft I xtending horizontally below the cross-bar I22, and shaft I05 carries at the opposite end thereof a small bevelled gear I06 meshing with a bevelled gear or pinion I01 formed integral with or suitably secured to a gear I09. This gear I09 is carried by a shaft, or pinion, I08, rotatably supported by bracket I mounted at the front of the typing machine, midway the width thereof. And the ing member 3. This member H3 is of substantially triangular shape and at its upper end carries an upwardly extending actuating arm H3, which projects upwardly and is of such length that its upper end portion may be readily grasped to shift the said member H3 from one position of adjustment to another position. At one side of said member H0 is rotatably mounted a gear H0 which meshes with the gear I09 and is adapted to mesh with the gear II? carried by spindle H3, adjacent spool I9. At its other side, the saizl member H3 carries a second gear, or pinion, H2, meshing with an'idler gear H I which, in its turn, meshes with the gear I09. Referring to Fig. 3, it will be seen that when the said member H3 is in one position of adjustment, the gear I10 will mesh with the gear H1 adjacent ribbon spool I9 and, at this time, the gear H2 will be out of mesh with the gear Ii'l adjacent ribbon spool 20. By grasping the handle H0 (upwardly extending arm) of the said member H3, said member may be swung'about the pivot shaft 108 to a position of adjustment which will move the gear H 0 out of engagement with the gear I 5'], previously engaged thereby, and the gear H2 will be moved into mesh with the gear of ribbon spool 20, or the gear lll adjacent said spool 20. Therefore rotary motion may be selectively trans mitted either to the ribbonspool I9 on the left, or to ribbon spool 20 on the right. When rotary motion is transmitted to one spool, the other spool runs free. A slot H5 is formed in the upper portion of the said member II3, transversely thereof, to receive a threaded pin I I4 which serves to limit swinging movement of the said member II3 andln addition it carries a winged nut 4' adapted to b tightened and apply locking presis in use, the keys are operated in the usual manner and the carriage moves step by step leftwardly. As the carriage moves towards the left, a rotary motion is imparted to the spring drum and the gear teeth of the spring drum, which mesh with the gear I0l, will impart rotary motion to the shaft I02. Shaft I02 constitutes the main drive-shaft for the ribbon mechanism and, as said shaft turns, rotary motion will be trans mitted to the shaft I05 from which rotary motion is transmitted by the beveled gears I00 and I01 to the gear I09. The gears H0 and III continuously mesh with the gear I09 and, during rotation of the gear I09 rotary motion will be transmitted either to the ribbon spco] I9 or to spool 20, depending upon the position of the said member H3. Since both spools receive their rotary motion from the gear I09, either spool may be turned with equal force and with equal velocity, as each is subjected to substantially the same frictional resistance created by the in term'eshing gears of the shafts I02 and I05. Therefore the typing machine may be operated as easily when the ribbon is moving into spool I9 as it can when the ribbon is moving into spool 20. Another way or stating this is as follows: The amount of power required to rotate spool 20 when the spool is nearly full of ribbon is substantially the same as the amount of power required to rotate spool I9 when that spool is nearly full of ribbon, but this power which is exerted by means of the carriage driving springof drum I and the shafts I02 and I05 and is transmitted to gear 409' is substantially the same as transmitted to gear IIO when meshing with gear II'I adjacent spool I9 as it is when transmitted to gear I,I2 when meshing with gear II'I adjacent spool 20. However, lengthy tests made with the 'very typing machine described hereinbefore the conventional spools v and ribbon reeling mechanism and other parts, now discarded, were removed from said machine, and utilizing a writing ribbon of silk approximately 30 yds. long, proved beyond the slightest doubt "that there was much less power transmitted by means of the conventional shafts of said machine to the right hand spool. It was found that this same condition existed in other conventional typing machines tested. Therefore, it was found that the spring of drum I00 must be made tighter than would be necessary for the reeling of the writing ribbon from the right hand spool through the guides and in contact with tie inking wheels ofsuch a machine (as describe in detail in my United States Patent No. 2,158,944band into the left hand spool. Of course it will be understood that such spools are mounted on vertical shafts and the spools lie in a horizontal positionfl The ribbon spools of the present invention may be of very much larger diameter than the ribbon spools of usual typing machines, and that makes it advisable to make said spools of Dowmetall or other suitable light, strong material. I prefer to have the hubs of the spools of appreciably larger diameter than the hubs of the ordinary typing machine spool. The hubs of my spools may be 1% inches or even 2 inches in diameter. Many typewriter spools in common use all over the world are not larger than two inches in diameter. I may use spools whose diameter is as much as four inches. The advantages of such spools occupying a vertical position are great; Because of the large diameter of the hub as well as the flanges of the spool, the ribbon spool may turn very slowly at all times, even when the spool is nearly empty. When using a small, conventional spool which has a very small hub, it has been found thatwhen the right hand spool is nearly full, the left hand spool must unwind rapidly and this puts too great a pull or' tension on the ribbon and increases the difficulty of reeling the ribbon upon the right hand spool when an inking means is used. The gears III of the present invention may be approximately the size of the hubs of the spools I9 and and said gears mesh with gears I I0 and I I2 which are'quite small. In view of the fact that the spools I9 and 20 are disposed. vertically and turn about horizontally extending spindles H8, the frictional resistance will be almost entirely between the upper portions of the spindles and the portions of the hubs resting thereon. It will thus be seen that frictional resistance will be along a line constituting the upper portion of a spindle engaged by the portion of the hub resting thereon instead of being in a circular path as is now the case with the horizontally disposed conventional spool of the typing machines most commonly used which is mounted about a vertical spindle and resting upon a surface surrounding the lower end of the spindle.

Due'to the fact that the spools and their hubs are of large diameter, and they are turned at a very slow rate of speed even when almost empty,

. frictional drag of the writing ribbon is reduced with substantially the same drag of the ribbon when the spool is nearly empty as when it is full and we, at all times, have a smooth, emcient movement of the ribbon. In fact when the ribbon is almost entirely unwound from a spool of my improved construction, the ribbon is moving therefrom at substantially the same speed at of the ribbon when being wound into a substantially empty spool of conventional sort used in a conventional or usual ofllce typewriter.

While I have shown: a roller I25 mounted on bracket I24 (Fig. 2) as a guide means for ribbon I'I, any other suitable guide means may of course be employed.

It will be noted that drive-shafts I02 and I05 are always in the same relation to each other and when one revolves, the other always revolves; also when spool I9 or spool 20 winds the ribbon, the spool always receives power transmitted through both drlveshafts. In the conventional machine used for mounting the present inventions, .the drive-shaft in the front of the machine which is active when the vertical spindle of the right hand spool would turn to rotate the spool, remained inactive and received no power from the carriage driving spring in drum I00, when the left hand spool was rotating to wind up the ribbon.

,It is apparent that by the use of my inventions, typing machines may operate for years in busy offices at less cost for ribbons and with saving of. time and superior appearance of the writing may be had at all times.

The inking mechanism is similar in principle to the inking mechanism of my United States Patent 2,158,944 above mentioned. However, the present invention is made up of two separate devices and each inking device includes an ink reservoir. This reservoir is of improved construction suitable for use in typing machines which are left in a tilted position over night and there is no danger of ink leaking out even though a fairly thin pigment ink might be used for special work which requires such thin ink.

When the present invention is in use, the inking devices are mounted in the typing machine back of the winding spools with the inking wheels near the writing paper 5n said machine and with the ink reservoirs directly in front of and slightly above said wheels. The ribbon II extends from one spool over guide roller I25 (Fig. 1) and through the guides and the ribbon vibrator and again through another set of guides 25, 26 and over roller I25 to the other spool. The ribbon I1 is always in contact with the peripheries of the inking wheels regardless of which inkin wheel is feeding ink or evenif for suitable reason no ink whatever is being fed ".0 ribbon II. The movement of ribbon I'I rotates the inking wheels and the inking rollers and the ink agitators. The tension and guide means shown are for maintaining the ribbon taut as it unwinds from the spool. It is preferable to apply ink to the path on the ribbon made by the type in writing but if a, very thin ink is used, the ink may be applied above I i from the typing position towards the spool which is winding up the ribbon. If for any reason it is desirable to stop the feed of ink to the ribbon, the arms I- (Fig. 2), may be moved inwardly and the inking wheel III will be moved out of contact with the ink screen or the ink on inking roller. At any time it is desirable to feed ink to said ribbon, the arm I is drawn outwardly. As illustrated in Fig. 2 at 31 and at 38, I prefer to use a small gear below the inking wheel and a large gear for the ink roller. The ink roller is preferably of metal.

I prefer that th narrow writing ribbon contact the inking wheel along a portion only of one face and that the opposite face run free of contact with any member of any kind at this point, but if desired the ribbon may contact a pulley along that face which is away from the inking wheel.

The spooling mechanism of the present inventions is much more efficient than the spooling mechanism heretofore used and even for machines which have no inking means for renewing the ink supply of the writing ribbon, a large saving in expense might be had by reason of the saving in buying only one spool ofribbon instead of seven spools, thus buying only one metal spool and one box, and requiring the labor at the ribbon factory of winding one ribbon instead of seven ribbons; also the labor of boxing one instead of seven.

It is understood that the constructions shown are for purposes of illustration only, and vari-- ations may be made in sizes and styles of parts and in many details without departing from the scope of the present invention. I do not limit myself as to the position of the inking rollers or inking wheels or ink reservoir or reservoirs.

I do not limit myself to the use of any one kind of ink, although I prefer-to use carbon'black ground in oil and mixed with dye and oleic acid and then put into small tubes for replacing the ink supply in the reservoirs 22. Please note screws 7 of Fig. 1.
